82 Claims.

The present invention relates to shoe machines and methods and is herein illustrated in itsapplication to. machines and methods for use in assembling and shaping counterstiieners and shoe uppers off the last.

In assembling counter stiffeners in lined uppers, it is the usual practice to apply adhesive to the counter stiiener and manually to insert the stiiener, which in most cases is amolded counter, between the lining and upper at the rear or heel portion of the shoe and then to apply-pressure manually to the heel portion ofthe lining and upper in order to secure a permanent bonding of said parts. This method of assembling uppers and counters is slow and unreliable and when the Cil assembled upper is lasted, the lasting stresses. y

often cause the counter wings to move heightwise of the upper so that it is necessaryto relo- Vcate the counter wings before the heel seat lasting operation.

It is an object of this invention to assemble counter stiieners and shoe uppers off the last under conditions similar to those to which Athey will be subjectedl during the subsequent lasting operation and thereby to eliminate the tendency of the wing portions of the counter to move out of position when the assembled upper is lasted. 'To this end, the invention in one of its aspects relates to the method of assembling counters and uppers oi the last, which comprises assembling a counter and an upper, stretching the assembled upper in a lengthwise direction and, while -it is under lengthwise tension, exerting pulls on stresses, and shaping the heel end of the assembled upper while subjected to these stresses to the lasting margin at selected side portions to se't up in the upper stresses similar to lasting l bond the parts together under lasting conditions.

In the practice of this method, as described herein, pulls are exerted on the lasting marginof the upper in the shank section to produce stresses similar to side lasting stresses .and adjacent to the opposite ends of the tip line to duplicate pulling over stresses.

In another aspect thereof, the invention ccmprises immersing a counter in liquid cementand raising it to a draining position; then transferring the counter to a predetermined assembling position and positioning a lined upper about it,

and, when the upper is properly positioned, holding the 'top margin thereof while wiping the rear part of the lining toward the counter flange.

It is another object of this invention to provide an improved machine for the practice of the above method. To this end, the illustrated machine is arranged to hold an assembled upper at selected points and is provided with an upper shaping form which is moved into and out of the supported upper to preshape the upper and to subject the upper to stresses similar to the stresses to which it is subjected in lasting. The

holding means consists of grippers which are Y Another feature of this invention relates to' the mechanism forfacilitating the assembling of a cemented counter and a lined upper. This mechanism is arranged to hold a cemented counter and a lined upper in determinate relation to each other, the upper being held about the-heel end and in the shank and tip sectionsso that it is adequately supported, leaving both of the operators hands free to smooth the lining over theinner side walls of the supported counter.

When assembling a counter and an upper, the operator frequently pulls the wings of a molded counter widely apart so that it will iit more readily into the pocket which the operator has to form between the upper and the lining with one hand while he inserts the counter with the other.

When the counter wings are stretched in this manner, the counter loses its molded shape and the wings tend to remain wide apartI with the result that they cannot perform their intended function of causing the heel end of the shoe to hug the foot of the wearer. With this in mind,

r it is a further object of this invention to provide mechanism for handling counters which will not pull or stretch molded counters out of shape during the cement applying and the assembling y counter transfer unit is arranged to lift the ce' mented counter off the counter carrier with a movement having rearward and heightwise components such that the counter carrier passes through the relatively wide foot'opening in the vcounter `and does not distort or spring apart; the

side walls of the counter. The counter is held in an upright position on the counter support so that the operator can use both hands in placing the lined upper about the counter.

In accordance with a further feature of vthis invention, the cementer counter is automatically clamped'on the counter support as soon as it is placed'thereon by the counter transfer device, and to this end a latched counter clamping membery is automatically released bythe counter transfer operating mechanism as the counter is placed on the counter support.

Invention is also to be recognized in the provision of an interlock between the side gripper operating mechanism and the clutch control which 'insures that the grippers are connected to the upper before the shaping form is moved into it,

thus making sure that the desired stresses are set up in the upper by the shaping form; in an improved stretching device which pulls the marnovel back seam gripping mechanism which ten- `V sions the heel end of an upper in a heightwise vdirection and holds it in that condition during the assembling andshaping operations.

These and other features of the inventionwill appear more fully from the following detailed description when read in connection with the accompanying drawings and will be pointed out in the appended claims.

Before commencing a detailed description of this machine; a brief outline will rst be given of an upper and counter assembling and shaping operation as it is carried out on the machine. A molded counter is rst placed flange up on the counter carrier in a cement pot Il (Figs. 6 and 8) and is then manually dipped into the quick-setting variety.V After the counter is dipped, it is raised to a dripping position and theA first part of the power cycle of the machine is initiated by the operator. This causes a counter transfer mech- -anism to pick the counter off the carrier in such the counter support in 5 manner as not to spring or bend the counter out substantially on line XII-XII of Fig. 3 and 75 of its molded shape and to transfer it flange down onto a U-shaped supporting member 58 located on the machine head where the counter is held during the subsequent assembling operation. The machine is then automatically stopped,- whereupon the operator positions an upper around the counter and clamps gripping devices to the top and bottom of the rear portion .of the upper, and to selected marginal portions of the upper in the shank and forepart, and locates the toe of the upper with respect to a toe gripper which is subsequently operated. After attaching the gripping devices, the operator uses a forming tool or the like to smooth the lining againstthe counter (Fig. 25).V of the power cycle of the machine is then initiated and causes an upper shaping form 210 to move into the upper, stretching the same into approximately the shape it takes when lasted and at the same time pressing the lining against the counter, thereby causing the two to be firmly bonded together. As the form moves into the 1.,

upper, the toe gripper grasps the toe end of the upper and exerts a longitudinal pull thereon which, together with the strains exerted by the side grippers, substantially duplicates in the upper the lasting strains so that the lining, counter and upper will be shaped about the heel end of the form 210 and firmly bonded together in their proper relative positions. The form remains in the upper -a short interval after which it is automatically moved out of the upper and, as itmoves The second part a dipping handle 3.6 having a depending arm 40. The upper position of the counter carrier (Fig. 12) is determined by a stop screw 42 which f to a rearwardly-located pin 39 that juts out from the side wall of the pot. n G

Counter transfer mechanism When counters are molded, their edgesare curved inwardly to form a reduced opening which will cause the heel portion of a shoe to hugthe foot of thev wearer. During the assembling opleration, itis important that the counters be handled4 in such manner that the side walls are not bent or opened to a degree which will 'cause thel counters tol lose their molded shape. To this end, it is contemplated that when an operator away fromA the upper, a tripping mechanism is caused to release the grippers so that the assembled upper can be removed from the machine.`

Referring now to Figs. 1 and 6, it will be seen that the machine frame comprises a hollow base I which encloses the treadle mechanism of the machine and a head I2 which forms a housing for the major part of the operating mechanism of the machine. Attached to the side of the head I2 (Fig. 3) is a cement pot I4 and means, which will now be described, for immersing a counter in the cement and handling itprior to the actual assembling operation.

Counter cementng unit The counter cementing unit-consists of the pot It which is open at the top and contains a sultable quick-setting liquid cement. Thepotis located on the left sidey of the machine with its upper surface at approximately the level of the places a counter on the cement pot support, he will present the counter, flange up, 'to the plate 20 with the wide portion of the front opening of the counter opposite the end of the plate 20. The operator `will then move the counter lforwardlyJ until the wider opening in the heel portion of the counter is reached and then downwardly to engage its rear wall with the clip 2d and to bring the counter flange into alinement with the plate 20. After the counter has been dipped in the cement and returned to the dripping position shown in Fig. 8, it is removed from y the support by a counter transfer mechanism rearwardly of the cement pot counter support of a molded counterand prevent it from tilting l when immersed inthe cement. The plate is provided with a depending flange 22 (Figs. 12 and 26) having a clip 2d which is adapted to engage the back of the counter and hold it in a vertical position with its inturned flanges positioned opposite to the sides of the plate 20. The plate is supported by a pair of spaced parallel links26, 2B which are pivoted at one end to heightwisespaced points on the depending flange 22.4 The lower link 28 is fastened at its other end to a pin 30 carried by a -bolt 3l mounted in the en d wall of the pot I4, while the other end of the upper link 2B is connected to a shaft 34 which is journaled above the pin 30 in the side walls of the pot. Due to the parallel arrangement of the links 26, 2B, the plate 20 is held in a horizontal plane during the dipping operation so that the walls of the counter will be coated without getting cement on the inturned ilanges.

The shaft 34 of the pot It (Fig. 3) where it is connected to extends beyond the inner side and arev provided with counter gripping means consisting of a pair of bars 65 and 6B which are pivoted respectively on the ends of the levers and are each provided with two transversely-extending counter-gripping needles 1D. The levers 50, 52 are pivotally mounted one one end of a crank arm 54 and are caused to move in unison toward and away from each other by intermeshing gears 62 and 54 formed on their adjacent ends. The other end of the crank arm 54 is provided with a collar 55 which is clamped to a hollow shaft 55 that extendsy longitudinally of the machine midway betweenthe cement pot counter support and a U-shaped counter support 58 (Figs. 8 and 20) mounted on thetop of the head I2.

Thelcounter gripping means is caused`to take hold of and release a counter by the action of t a link 82 (Fig. 3) which is connected to the lever 52 and rotates the same when moved forwardly or rearwardly with respect to the arm 54 by the movement of a longitudinally reciprocating rod 84, as hereinafter described, rotation of the lever 52 causing -a corresponding vmovement lof the lever 5i) through the action of the gears 62, 64. After the counter gripping means takes hold of a counter, the shaft 56 is rotated to transfer the counter to the U-shaped support 58,`the rotation of the shaft being effected by the action of a segmental gear 'I6 on an elongated pinion I4 which is fastened to the rear end of the shaft 56. When the arm 54 is rotated, the link 82 is caused to the bearing during the early part of the counter transferring operation to move the wider part ofthe counter opening at the. front of the counter opposite the plate as the counter is raised from the carrier bythe arm 54 and thereby avoid opening the counter wings an appreciable amount when thev counter is moved upwardly Y past the plate. The teeth on the pinion 14 are of such length that they will remain in mesh' with the teeth in the gear segment I6 at all times during the axial movement of the shaft 56.

The hollow shaft 56 is moved back and forth in the bearing 60 by the rod 84 (Figs. 3 and 9) which 'ls mounted in the hollow shaft and is frictionally coupled with the shaft by a springpressed bar 86 which is seated in a groove formed in the rod. The bar is forced against the inner wall of the shaft 55 by a long bowed spring 88 (Fig. 3) which is conned between the back of the bar 06 and the bottom ofthe groove formed in the rod. Thus, when the rod 86 is reciprocated, the friction betwen the bar 86 and the inner wall of the shaft 56 will cause the shaft to move with the rod until either the sleeve '55 or the pinion 74 strikes an end of the bearing whereupon the shaft 56 will stop and the rod 84 will continue its movement. lIhe mechanism which reciprocates the rod 64 is arranged to continue the movement of the rod for a short distance after the movement of the shaft 56 has been stopped by the bearing 50 and this additional movement of the rocl is utilized to open and close the counter gripping means. The control of the counter gripping, means is effected through the link 82 which is connected to the rod 84 by a plate 81 (Figs. 3 and 23) attached to an arm 85 formed on the rearwardly projecting end of the rod 84'.

The rod 84 and the pinion 14 are operated by a cam 92 (Figs. 11 andl) mounted on a shaft 94 which is coupled toy the main drive shaft of the machine by a clutch 96 (Fig. l). The cam 92 is located outside of the head l2 adjacent to the cement pot I4 and controls the pinion 14 through a lever 98 which is connected at its upper end to the pinion 14 by a gear segment 'I6 and at its lower end to the cam by a follower roll 95 which travels in a peripheral cam groove 53. The lever 08 is pivoted intermediate its ends on a bolt 99 which extends longitudinally of the head i2 and is supported by a lug @l that projects out from the side wall ofthe head. The cam 92 controls the movement of the rod 54 'through a linkage system consisting of a bell crank lever |00 one arm of which is connected to the rod 04 ky a link |02 and the other arm of which is connected by a link |04 to a cam follower |03 which travels in a cam groove |05 (Figs. ll and 18) formed in the side of the cam 92 adjacent to the side wall of the' head i2. The cam follower |03 is also connected to one end of an arm |06, the

other end of which is pivotcd on a transversely extending bolt- |08 (Figs. 18 and 19) mounted in the side wall of the head |2 beneath the pivot of the lever |00. I

A better understanding of the counter transfer mechanism can probably be had from a description of its operation. At the beginning :of an assembling operation, that is, when a counter is placed on the cement pot counter carrier, the arm 54 is positioned a slight distance rearwardly of the position shown in Fig. 3, and the clamping levers 50, 52 are spaced wider apart than they are shown in that ligure. When the counter is ready to be taken oi the support, the operator initiates the rst machine operation by moving the clutch lever 214 to the right, as viewed in Fig. 1. This causes the rod 84 to move to the left, as viewed in Fig. 3, carrying the shaft 56 and arm 54 with it until the pinion 14 strikes the bearing 60 after which continued movement of the link 82 causes the levers 52 and 50, through the action of the gears 62,64, to move inwardly toward each other until the needles l0 grip the sides of the counter. Axial movement of the rod 84 is then stopped fora moment and the shaft 56 is rotated to release the counter from the latch 24 (Fig. 26) and raise the inturned counter flanges above the plate 20. As the counter anges move above the plate 20, the rod 64 is moved sharply to the right, as viewed in Fig. 3, partly to withdraw the counter from the support while the plate 20 is in the relatively wide midsection of the counter. During this movement c-f the rod 84, the shaft A5|i continues to rotate but at a slower rate and concomitantly raises and tilts the counter so that the counter assumes an angular relation with respect to the plate 2li. Aft-er the counter assumes a desired angular relation with respect to the plate 20, the rate of the rearward movement of the rod 84 is reduced. Continued rotation of the shaft 56 causes the plate 20 to pass through the top and front counter openings thus effecting the' withdrawal of the counter without appreciably springing its side walls. the shaft 56' until the counter is seated flange downward on vthe U-shaped support 58 (Fig. 20). When the counter is seated on the support 58, a clamping iinger (Figs. 18 and 24) is moved, in a manner which will hereinafter be described, to

' a position where it clamps the inturned counter flange against the support 58. As the counter is clamped against the support 58 by the finger 90, the arm 54 strikes the bearing 60 stopping the rearward movement of the shaft 56. The rod 64 continues to move to the right after the arm 5ft stops, thereby causing the link 82 to move rearwardly relatively to the arm 54 and move the clamping levers 50, 52 away from each other sufiiciently to release the counter. When this is done, the gear segment 16 reverses the direction of its movement and moves the arm 54 backward to its position at the beginning of the operation.

This position is opposite to the full line position of the arm 54 shown in Fig. 20 and itA will be seen that that position is rearwardly of the dotted position of the arm 54 which is the location of the arm when the counter is placed on the support 58. v

Upper assembling After a vcounter has been clamped upon the spport 58, the operator takes a lined upper in his hand, separates the quarter lining from the upper, and slips the upper over the counter, the

tcp of the head |2 and` the back side of the sup-- The gear segment 16 continues to rotate by a headed screw `the block |44. The block The spring |56 also upper along the back seam and stretch Ithe heel end of the upper in a heightwise direction; a pair of widthwise-spaoed grippers which grasp l, the lasting margin in the inside and outside when the upper shaping form stretches the up-l per as will subsequently be fully described.

The back seam (Figs. and 18) having an enlarged head which is arranged to clamp the lasting margin of the upper against the back side of the support 58, and a pair of gripping jaws |22, |24 which grip the top portion of the upper at the back seam. The bar is pivoted to an arm |26 of a hand lever |28, the bar |20 and the arm |26 forming a toggle which, when straightened, clamps the upper against the support 58 and holds the lever |28 in the upright position shown in Fig. 16. The lever |28 is pivoted on a pin |30 (Fig. 5) which is mounted in openings formed in ears |32, |34 that project from the top of the casing |2. The upper jaws |22, |24 which take hold of the top portion of the upper are carried by an assembly which is arranged to be rocked back and forth between an inoperative position shownin Fig. 18

and an operative position shown in Fig. 16. The jaw |24 is formed on the forward yend of a channel-shaped member |36 that is swingably connected to the top of the casing I2 bya pair of supporting membersr |38 (Figs. 5 and 18) grippers lconsist of a bar |20V ward movement of the arm 66 causes a corresponding upward movement of the link |68 which lifts the front end of the member |36 about its vpoint of connection with the links |38 as. a center; thelinks |38, being anchored to the top of the head I2, act as a fulcrum for'the member |36. The upward lmovement of the front end of the member carries thejaws |22, |24 upwardly,

thereby stretching the back part of the upper in a heightwise direction. The back portion of the upper is positively held under tension while the which are Apivoted at their upper ends to the member |36 and are connected at their lower ends by screws |40 to a pair of apertured ears |42 which project up from the top of the casing.

The jaw |22 lconstitutes the forward face of a.

block |44,which is slidably mounted in the groove formed on the under surface of the channelshaped member. |36 and-is held in that groove stud |58 on a rearwardly extending arm |60 (Fig.

25) that is loosely mounted on the pin |30. The arm |60 is connected to the lever |52 by a pair of links |62 so that the upward pressure exerted by the spring upon the arm is transmitted to the lever and tends to straighten the toggle and thereby force the block |64 toward the jaw |24. tends to lift the front end of the upper gripper. This is due to the fact that the other end of the spring |56 is hooked beneatha stud |60 (Fig. 5) projecting from a forwardly extending arm |66 which is also journaled on the pin |30, the arm |66 in turn being connected by a link |60 to the forward end of the member |36.

When the jaws |22, |20 grasp the upper, the arm |66 is urged upwardly by the action of the forwardly extending end of the spring |56. Up-

|48 which extends downwardrear portion of the form 210 downwipes the lining by a detent comprising a 'one-way clutch' which permits the arm |66 to move upwardly to tension the upper ,but prevents its downward movement. The one-way clutch consists of a segment |10 (Figs. 5 and 25) which projects rearwardly from the hub of the arm |66, and a brake arm |12 which is in alinement with the segment .|10 and is lpivoted on a rearwardly-loi catedtpin |14. 'I 'he arm |12 engages the face of the segment |10 below the line of centers extending between the pins |30 and |14 and is urged upwardly by a spring |16 (Figs. 18 and 25) that engages the under side of an arm |18 which projects from the hub of the brake arm |12. Whenvthe toggle |52, |54 is broken (Fig. 18) the links |62 are displaced downwardly from the member |36 and as the arm |18 engages the lower ends or these links (Figs. 5 and 25), it will also be displaced downwardly a suicient distance to carry the brake arm |12 out of engagement with the face of the segment |10 whereupon the upper gripper assembly can be moved freely back and -forth about the pivot pin |30.` When .l

the toggle is broken at the end of an assembling operation, a spring-pressed latch mounted on the rear end of the member |36 snaps over the tail end of'the lever |52 and holds the toggle in its broken-position and the one-way clutch in an inoperative condition until the operator releases the latch to clamp the upper gripper to an'upper during the next assembling operation.

The operation of the back seam grippers will now be described. Assuming that an upper has been placed in the position shown in Fig. 18, the operator rotates the lever |28 in a counterclockwise direction to straighten the toggley formed by the arm |26.and the bar |20, thus clamping the margin of the upperagainst the back face' of the support 58. The operator then graspsthel ymember |36 and moves the whole upper gripper assembly comprising the member |36 and the links |38, |62 and |68 forwardly until the open jaws |22, |24 lie above the back portion of the upper when he presses down upon the member |36, causing the arm |60, |66 to move downwardly about the pivot pin |30 and swing the member |36 downwardly. about its pivotal connection to the members |38 until the jaws |22, |24 are in position on opposite sides of the top portion of the upper. He then releases the latch |55 allowing the spring |56 (Fig. 5) to straighten the toggles |52, |56 and cause the jaws |22, |24 to grip the upper between them whereupon he removes his hand from the member |36. Upon release of the latch E55, upward movement of the arm and links |62 allows the arm |18, which underlies the arm i60, to move upwardly under the urging of the spring |16 and bring the face of the brake arm |12 into one-way locking engagement with the face of the segment |10. This locking engagement prevents further counterclockwise movement of the segment |10 and arm |66 which is connected thereto 'and as the arm 65 is connected tothe forward end of the member |36, it also prevents the upper gripping jaws from.P moving downwardly. However, if there is any slack in the back portion of the upper, the spring |56 which tends to raise the arm |66 will rotate that arm in a clockwise direction until the back of the upper is taut, rotation of the arm |66 in that direction being permitted by the one-way clutch.

After the back seam has been gripped by the back seam grippers, the operator then places the lasting margin of the inner and outer shank portions of the upper between the jaws of a pair of widthwlse-spaced grippers |82, |84 (Fig. 3) located on opposite 'sides of the upper, and the jaws of the grippers are then closed against the upper by treadling a lever |88 (Fig. 2). As the construction of the different side grippers is the same, only the typical gripper shown in Fig, l() will be described in detail, and like numerals will be given tothe similar parts of the dierent grippers. Referring to Fig. 10, the gripper comprises acylindrical sleeve |80 which is freely mounted on a rod that is supported by the side walls of the head i2. Extending upwardly from the sleeve |98 isa plate |94 having an inclined slot 88 formed in its upper portion and a jaw |96 on its free end. Pivotally connected to the plate 84 by a pin |98 is a second plate 285i having a jaw 202 formed on its end opposite the jaw Hi8 and a straight slot 204 in its lower portion opposite the area in' which the inclined slotl :|88 is formed in the plate E84. The jaw 2h12 is moved toward and from the jaw tt by a pin ,288 which extends through the slots H98 and 208 and is connected at its ends to downwardly extending links 288 and 2 i8 (Figs. l and 16) located on opposite sides of the plate ld. The lower ends of the links 208, 2H) are connected by pins 2li tothe arms of a forked operating lever M2, one end of which is pivoted at 2M to the sleeve G88 and the other end connected to a treadle.

The shank grippers |82, i8@ are pivoted on a rod 82 (Fig. 16) which is mounted in alined openings in the side walls of the head I2, the gripper-operating levers 252 projecting out through openings formed in the side walls adjacent to the bearings for the rod |92. projecting ends of the lever 2 i2 are connected by links 2lb to the projecting ends of a yoke Zit which extend outwardly through openings 228 in the casing i8. The yoke is connected intermediate its ends to the upper end of a link 222,.

the lowerend of which is connected through a relief spring 228 and a lever 23@ to the treadle 585.

The connection between the lower end of the link 222 and the lever 230 consists of a sleeve 22d which is slidably mounted on -the link between a collar 226 and the relief spring 228, the spring being held on the link" by nuts 228. 'Ihe relief spring 228 protects the gripper mechanism from excessive treadle pressure by permitting the sleeve 224 to move downward relatively to the link 222 after the gripper jaws have been pressed against the work. The sleeve 224 is connected to the forward end of the lever 238 which is in turn pivoted intermediate its ends on a shaft 232 that also supports the treadle |88. The lever 230 is connected with the treadle y|88 by a laterally extending arm -234 (Fig. 2) which underlies the treadle |88 and is held against the trea- The dle by a spring 433 (Fig. 1) when thegrlpper jaws are released. When the lever 230 is de- Iwalls of the head i2.

. pressed to close the gripper jaws, it is held in that position by a spring-biased latch 285 which snaps beneath a finger 235 formed on the rear end of the lever. After the lever 23|) is latched, the operator releases the .treadle |88 which s returned to its upper position by a, spring 434 (Fig. 6). When the latch 265 is released, the spring 433 raises the front end of the lever 230, thereby effecting the opening of the jaws of the grippers |82, |84.

Having clamped thegrippers |82, |84 to the shank portion of the upper, the operator next places the lasting margin at the opposite ends of the tip line between a pair of widthwise-spaced grippers 238, 238 (Figs. 3 and 4) and then closes the jaws of those, grippers by depressing a treaidle 240 (Fig. 1). The grippers 236, 238 are pivoted on a rod 242 journaled in the side walls of the head at the front end of the machine. The operating levers 2|2 of the grippers 236, 238 are connected to the treadle 240 by a pair of links 244 (Fig. 6) which are pivoted at theirupper ends, respectively, to the ends of the lever 2|2 and at their lower ends to a yoke 246, the yoke in turn being connected intermediate its ends tothe upper end of a rod 248, the lower end ofwhich is connected to a lever 252 by a sleeve 250 which is 'slidable on the lower end of the rod betweenv a collar 256 and a relief spring 254. The lever 252 is journaled on a. shaft 258 which also serves as a mounting for the treadle 24U (Fig. 2) and is connected to the treadle yby a laterally extending arm. 24|. The jaws of the grippers 236, 238 are held which snaps beneath a flnger 288 formed on the rear end of the lever 252 when that lever is depressed by the treadle 24|) so that lthe treadle can then be released and returned to its upper position by a spring 430. When the latch 265 is moved out from under the finger 288 `by a release mechanism which will presently be described, a spring 432 connected to the forward end of the lever 252 raises that lever and thereby Sisfecs athe opening of the jaws of the grippers 3 After depressing the treadle 248, the operator next places the tip end of the toe portion of the upper between the open jaws of the toe gripper 286 (Fig. 18) which does not take hold of the upper until the next machine operation when the upper shaping form 2li) is moved upwardly into the upper. The toe gripper 288 consists of a lower jaw 349 (Fig. 18) formed on the upper end of an arm 358 which is pivoted on a transversely extending rod 35i supported by the side The upper jaw 3137 is extending arm of a bell 348 which is pivoted on the upper end of the arm 350, the lower arm of the bell crank lever being connected by a :pin-and-slot connection to the .upper end of a lever 344 which is in turn pivoted intermediate its ends on the rod, 35|. The forward edge of the arm 350 has formed thereon an aperturedboss in which is mounted a cross arm 348 (Fig. '3) which is connected at its ends, respectively, to the grippers 236, 238 by springs 352, 354. When the toe gripper 266 is clamped against the upper and is moved forwardly to exert a longitudinal pull on the upper by a mechanism which will lbe hereinafter described, the springs 352, 354 exert a forward pull of the tip line grippers 236,238, causing them to exert a forward pull on the side portions of the upper.

When all of the grippers are properly adjusted,

formed by the rearwardly crank lever shut by a spring-biased latch `2654 (Fig. 1)

tions of the counter does away with the possibility of creases being formed in the liningin that area during the subsequent heel shaping operation. The wiping action of the tool also causes the adhesive to ow downwardly from the side walls of the counter and coat the top of the counter flange, with the result that the portion of the lining which overlies the flange will be bonded to it when the two are pressed together by the heel end of the form 210.

Upper stretching and shaping into the upper and as the form moves upwardly, the jaws of the gripper 266 are closed about, the toe end of the left, as viewed in Fig. 18. Movement of the gripper in that direction pulls the upper taut longitudinally against the heel end of the form and also causes a corresponding movement of the tip line grippers 236, 238, which sets up a longitudinal pull 0n the sides of the upper. The upward .movement of the form 210 stretches theA upper in a heightwise direction, and the instep portion 213 of .the form under the influence of a spring the upper and the gripper is moved to,

the heightwise movement of the forepart of the form beingl controlled by the groove 282 and effected through a linkage system consisting of a link 284, lever 286, and link 292. The link 284 is pivoted at its forward end to the lower portion of the lever 266 and at its rearward end to head of the clampingiinger 60,-in

' lposite side of the cam 280.

These operations cause the upper shaping form.210 to move up heel end first 215 supplements that action in the instep portion of the upper, with the result that the pull exerted by the tip line grippers 236; 238 dupli- V cates pulling over stresses, and the pull from the shank grippers |82, |84 duplicates the side lasting stresses. As the form is moved into the upper, the heel end of the form is swung rearwardly and downwardly until it is stopped by the support 58. Shortly before the heel end of the form reaches the support, it contacts the lower portion of the lining and wipes the lining downwardly as it moves toward the support. The pull exerted on the upper by the grippers causes the heel part oi' the upper to lie tightly against the heel end of the form, thereby shaping the heel end of the upper about the form and firmly bonding the lining, counter, and upper together in proper relation to one another,

while the pressure of the bottom of the form against the underlying lining margin and counter flange firmly bonds the two together. After a short interval, suicient to permit the quicksetting cement to form an initial bond between the lining, counter, and upper, the form is moved out of' the upper and all of the grippers are automatically released.

The mechanism for effecting the above operations consists of a cam 280 which is located within the head i2 and is keyed to the driven shaft 98 (Fig. ll). The heightwise movement of the form 210 (Figs. 16 and 18) is jointly controlled by cam grooves 282, 404 formed, respectively, in the opposite side facesof the cam 280.l

a cam follower 281 (Fig. 1'7) which travels in the groove 282. The cam follower isalso connected to the upper end of an arm 288, the lower end of which is journaled on a rod 290 (Fig. 16) fastened to the side walls of the head |2 below the cam 260. The lever 286 is pivoted intermediate its end on a bolt 29| which projects inwardly from the side wall of the head I2 and is connected at its upper end to the link 292 which is in turn connected to the upper shaping form 210 by a pin 294. The lever 286 and the link 292 form a toggle which, as it is straightened, raises the forward end of the form 210 to the position shown in Fig. 16 and finally forces the heel end of the form against the counter support 58. vAs the forepart of the form 210 is rais/ed through the action of the cam groove 282 on itscontrolled linkage, the form is moved rearwardly by another linkage system which'is controlled by the cam groove 404 formed in the op- Thls linkage system consists of a lever 400, link 406 and a pair of swingably mounted arms 296, 298 (Figs. 18 and 22) which are connected at their upper ends to the form. The lever 400 is pivoted in its midsection ona' pin'40| (Figs. 11 and 16) and carries at its lower end a cam follower 402 which travels in the cam groove 404. The lower ends of the arms-296, 298 (Fig. 22)l are journaled upon a pair of studs 360, 362 which are'mounted in bosses 304 that extend inwardly from the' side walls of the head |2, while the vupper ends of the armsA are connected with the heel portion of the form 210 by a pin 306.

As the heel portion of the form 210 approaches the counter support 58, .the counter clamping finger 90 is withdrawn from engagement with the counter ilange and moved forwardly to the position shown in Fig. 16 where it lies within an opening 21| formed in the heel portion of the connected at one end to the upper portion of the lever 286 and at its other end to the arm 3v|0 of a cam 3|2 which is mounted on'a transversely extending rod 322 supported bythe side wallsA of the head |2. The face of the cam 3|2 engages a roller 3|4 on a slide bar 3|6 which is urged toward the rear of the head I2, or to the right as viewed in Fig. 18, by a spring 320 which is connected'at one end to the bar 3|6 and at its other end to the rear wall of the head. The rod 322 passes through an elongated slot 324 formed in the rear portion of the bar 3|6, the slot permitting forward or rearward movement of the bar with respect to the cam as different portions of the cam act on the roller 3|4 and cause the displacement of the bar. The forward end of the bar 3|6 is connected by a pin 326 to the upper end of a, supporting arm 328 which is pivoted on a rod 330. Also pivotally mounted on nected at one end to the nger 90 and at its;

other end to the rear end of the bar 316. When the upper shaping form 2li] is raised, the bar 3l6 is moved in a forward direction from its position shown in Fig. i8'. The initial portion of this movement causes the pin 335 to ride upwardly in the slot 338, thereby lifting the finger 90 from the counter ange, and continued movement of the bar after the pin contacts the rear wall of the slot carries the linger with it to the position shown in Fig. 16 where it is clearof the rear wall of the form Zlli.

Located rearwardly of the bar SIB is a latch 36!) which holds the finger @d in its inoperative position shown in Fig. 16 until the appropriate time during the counter transfer operation when a raised portion 356 of the cam 283 moves the latch to an inoperative position, thereby releasingthe linger and permitting it to clamp the counter flange against the counter support. The latch consists of a forwardly extending arm 354, which engages the rear end of the bar 3 I6, and a depending arm .364, which carries a roller 353 that engages the peripheral face of the\carn 28d. During the counter transfer operation, the raised portion 356 moves beneath the roller 353, causing the latch toV move sufficiently in a counterclockwise direction to carry the arm 364 out of engagement with the rear face of the bar 3ft, thereby permitting the spring 32u to move the slide 315 to the right, as seen in Fig. 16, and swing the finger 90 against the flange of a counter on the support 63. During the subsequent formand lays it smoothlyagainst the raising operation, when the bar 35S is moved forwardly, the raised portion 35d passes from beneath the roller 358, permitting a spring 3&2 located back of the arm 36H to move the latch in a clockwise direction until the :(inger engages the rear end of the bar and latches the finger in its inoperative position.

As the form 2l@ is raised, the lever 2% acting through a spring 3182, causes the toe gripper 26d to take hold of the upper and exert a lengthwise pull on the same, the spring 3&2 being connected at one end to the lower arm of the lever 28d (Fig. 18), which moves rearwardly during the upper-raising operation, and at its other end to the lower end ofthe lever 351213. When the lower arm of the lever 286 moves rearwardly, the pull of the spring 362 causes the lever 34d to rotate in a counterclockwise direction, as viewed in Fig. 18, and the upper jaw 3H to move against the lower jaw 349. After the jaws 3M, 34S!! grasp the upper between them, the toe gripperV assembly, consisting of theupper end of the llever 344,

the lever 346, and the arm 35D, moves as a unit to the left, as viewed in Fig. 16, and exerts a lengthwise pull on the upper. Movement of the arm 350 to the left pulls the tip line grippers in -that direction through the action of the springs 352, 356, thus tensioning the sides of the upper. The shank grippers 182, 184, being freely mounted on the rod |92, will move forwardly to adjust themselvesto whatever forward displacement there is in the shank portion of the upper acreage caused by the lengthwise pull imparted to it by the toe and tip-line-grippers.

IAs the form 21D moves up into the upper, the j lower portion of the lining adjacent the side walls of the counter is stretched inwardly away from the side walls, ln a manner which will now be described, so that the margin of the heel seat face of the form, as it moves downwardly, presses against the taut lining and lays it smoothly upon the inturned counter flange. When the operator smooths the lining against the inner walls of the counter, the margin of the lining will lie over the inner ends of a pair of transverse levers 368, 370 (Fig. 21) which are positioned opposite to the side walls of the counter (Fig. 3). The levers 368, 370 are pivoted, respectively, on pins 372, 314 mounted on ears on the top of the head l2 adjacent to the side walls, the outer arms of the levers projecting beyond the sides of the head and being urged downwardly by springs 375, while the inner arms of the levers extend toward the center of the head and are substantially V shaped so that they pass beneath the ilange of a counter on the support 58 (Fig. 20). As the heel end of the form 2lll is moved into the heel end of the upper, a bar 366 (Fig. 18) moves ahead of the heel end of the form and grips the lining ben -tween it and the ends of the levers 368, 310, as As 'the heel portion of theshown in Fig. 21. form continues to move toward the support 58, the bar 366 continues its downward movement, carryingthe levers with it, and thus pulls the margin of the lining downwardly, thereby causing the bottom portion of the lining to stretch inwardly from the side walls of the counter over the counter flange. While the lining is stretched in this manner, the margin of the heel seat face of the form 210 moves into engagement with the counter flange and as it does, it pulls the lining Yinwardly from the levers 368, 310 and the bar 366 counter flange as is indicated in Fig. 22.

The bar 366 is integral with the upper end of a slotted plate 390 (Fig. 21) which is located between the arms 296, 298 (Fig. 22) and is coupled with the arms by a pair of heightwise-spaced pinand-slot connections which permit the plate to move relatively to the arms. The connections `are formed by a pair of slots 392, 391i in the plate #39@ (Fig. 18), the slot 39d receiving the pivot pin 308 that connects the arms 2%, 2% to the form (Fig. 22) and the slot 392 receiving a pin dat extending between the arms 296, 29d. The lower end of the plate 396 is connected by a pair of links 38d, 386 (Figs. 18 and 2l) to the rearward .end of an oflsetr arm 31B, the forward endcof which is pivoted on a rod 380. The upper surface of the arm 318 engages beneath a roller 382 on the lever 286,`the location ofthe offset in the arm being such that when the lever is rotated to 'raise the form, the roller 382 passes over the offset and forces the arm downwardly, thereby causlng the bar 368 to move downwardly and stretch the lining.

After a short dwell in the position shown in Fig. 16, the'form 210 is moved back to the position shown in Fig. 18 and as it is moved back, the back seam grippers and the side grippers are automatically released by mechanism which will now bey described. The back seam grippers are released by a trip 40B which is pivoted on the link U6 adjacent to a depending nger Hoon the lever |28. When the link 406 is moved-to the right during the form raising operation, the trip 408 vsnaps beneath the finger 410 as it moves 'thereby effects the release of to the position shown in Fig. 16. Upon movement of the form downwardly from the upper, the link 406 is moved to the left, caus'ing the end of the trip 408 to strike against the flat side face of the finger 4|0 (Fig. 14) and rotate the lever |28 in a clockwise direction which raises the arm |26, breaking the toggle |20, |26 and releasing the lower back seam gripper, and also lowers a rearwardly extending arm 4|2 which overlies the pin |58 on the arm |60. Downward movement of the arm |60 breaks the toggle |52, |54 releasing the upper gripper and at the same time, effects the release of the one-way clutch by depressing the arm |18. Release of the one-way clutch permits the upper gripper assembly to move back to the position shown in Fig. 18 under the urging of the spring |56.

The side and toe grippers are released through the action of a trip-4|4 (Fig. 16) which is pivoted on the lower end of the lever 286 and acts upon 446 (Fig. 1) which passes over a pulley 448 fast to the motor shaft and a pulley 450 which is connected to the driving shaft. The driving shaft is connected with the driven shaft by intermeshing gears 454, 455 which are connected, respectively, to the driving and drivenl shafts (Fig. 3). and the driven shaft is, in turn, connected with the clutch by a worm 456 which meshes with a worm'wheel 451 on one member of the clutch 96. The clutch 96 is of the cyclic-operated type described and claimed in United States Letters Patent No. 2,221,875, granted November 19, 1940, on my application for improvements in Driving mechanisms. 0nly so -much of the clutch structure will be described as is necessary to'give an understanding of its operation in its present environment.

a latch-controlling bell-crank lever 4|6. When v the lever 286 is moved in a counterclockwise direction toraise the upper shaping form, the trip 4|4 snaps over the end of the lever 4|6, and upon its return movement, lt rotates the lever 4|6 and the latches 264, 265 through a linkage system, which will now be described. The .bell-crank lever 4|6.is connected by a link 4|8 (Figs. 1 and 18) to an arm 420 of a three-armed lever. A second'arm 422 of the three-armed lever hasV a shoulder formed thereon which lies behind the top edge of the latch 264, while the` third arm 424 is connectedlever 428 which controls by a link 426 to a second the latch 265. Upon the return movement of the lever 286, which takes place during the lowering of the form, the trip 4|4 strikes a nger 4|5 on the bell-crank lever 4I6, causing the same to move in a counterclockwise direction andl raise the link 4|8. This movement of the link 4|8 causes a corresponding movement of both the three-armed lever and the lever 428 which moves l the latches 264, 265 from beneath the grip-operating levers 230, 252. Release of the grip-operating levers allows the springs 432, 433 to move the levers in a clockwise direction and thereby cause the opening of the gripper jaws. As the lever 286 approaches its forward position (Fig. 18) the spring 342, which is a combined tension and compression spring, rotates the toegripper assembly in a clockwisedirection, releasing theV longitudinal pull on the upper, and opening the jaws 341, 349. i

When the cam in'Fig. 18, the driving mechanism is automatically disconnected, and as the grippers have all been released, the operator can removethe assembled upper from theV machine. At this time the parts, with the exception of the gripping finger 80 will be in the position shown in Fig. 18. The gripping nger 80 will .be held in the position shown in Fig. 16 by the latch 360 which is not released until another counter has been placed on the transfer phase of thenert assembling operation.

Transmission vand )clutch operating mechanism 280 reaches' the' position shown V support during the counterelectric motor 440 (Fig. 1)

by a transmission system shaft 442 (Fig. 16) a driven 'I'he clutch includes a pair of connected angularly-spaced dogs 458, 460 (Fig. 1) which disconnect the clutch when either of the dogs strikes a stop member 462. The stop member 462' is urged into the path of the dogs by a spring 464 and is moved out of that path by a shoulder 413 on a bar 468 (Fig. 17) which engages a shoulder 463 on the latch. The rear end of the bar 468 is pivoted to the forked head of a rod 466 which is slidably mounted in the front wall of the clutch housing. The rear end of the rod is fastened to aplate 461 which abuts the hand lever 214 and carries at its lower end a' pin 465 which extends into a recess in the casing and is urged |to the left, as viewed in Fig. 1, by a spring 469 which is confined in the bottom of' the recess. The pin 465, due to the action of the spring 469, tends to move the bar 468 to the left, as viewed in Fig. 1, and in addition, it prevents the rod 466 and the bar 4:38 from rotating and thereby moving out of proper relation to the other parts of the clutch.

At the beginning of an assembling operation, the dog 458 will be in engagement with the stop member 462 and will be displaced sufciently to disconnect the clutch. To start the rst part of. the power cycle of the machine, the operator moves the hand lever 214 in a clockwise direction, as viewed in Fig. 1, thereby displacing to the right the pin 466 and the bar 468. This movement of the bar carries the stop 462 out from under the dog 458, thereby permitting the clutch members to become engaged and rotate the cam shaft 84 until the stop 462, which has meanwhile been disconnected from the bar 468, engages the dog 460. 'Ihe disengagement of the stop member -462 from vthe bar is effected by a cam 410 on the periphery of one of the clutch members where it is disposed in the path of a projection 412 on the bar so that when the clutch is rotated, vthe cam 410 strikes the projectionl stresses will beset up in the upper when the clutch is operated a second time to move the form into the upper. The connections between the latch 414 and the treadle mechanism consist of a bell-crank lever 416 (Fig. 1), one arm of which is connected by a link 418 to the yoke 246 ofthe tip line gripper linkage and the other 'arm to a crank arm 480jby a rearwardly extending link 482 (Fig. 19). The crank arm 480 is fastened to one end of a shaft 484- which extends transversely of the head I2 and is connected at its other end (Fig. 14) to the latch 414. The link 482 is connected to the crank arm 488 by a loose connection which permits the latch to move rearwardly with the bar 468 without releasing the same in the event that the hand crank 214 is inadvertentlyv operated before the grippersv are properly adjusted. The connection between the link 482 and the crank arm 480 consists of a sleeve 486 which is pivoted to the crank arm and is slidable on the link between a collar 488 formed on the link and a spring 490 which surrounds the rear end of the link and is held thereon by a nut 492. When the tip grippers are closed by operating the treadle 240, downward movement of the yoke 246 causes a rearward displacement of the link 482 which disengages the latch 414 from the bar 468. When released, the bar moves up into operative engagement with the stop 462 so that the operator can forthwith release the second dog 460 by again operating the hand lever 214 and eiect the second part of the power cycl of the machine.

Operation of the machine In practicing the method of assembling shoe uppers and counters in accordance with the present invention, the operator first attaches a counter to the counter carrier in the cement unit and dips it into the quick-setting cement contained in the pot I4. After the counter has been dipped and the counter carrier moved up to its raised position shown in Fig. 11, the lever 214 is operated to start the first part of the power cycle of the machine. During this cycle the counter is gripped by the needles 10 on the gripping levers 50, 52 and is transferred, flange down, to the assembling support 58,`and as the counter is placed on the support 58, the latch 360 is depressed by the projection 356 on the cam 280 and is moved downwardly 'out of the path of the plate 3|6. Release ofr the plate 3|6 allows the spring 320 tb cally stopped by the engagement-of the stop 462 with the dog 460.

The operator now connects theback seam grippers |20, |24 to the rear portion of the upper, locates the margin o'f the upper properly with respect to the shank and tip line grippers and treadlesy the same, and then places the toe end of the upper between the jaws of the toe gripper. The operator next smooths the lining against the inside of the counter by the use of a convenient tool such as the blade 212, vand ,after the lining has been smoothed, he again operates the lever 214, causing the machine to go through the second part of 'the power cycle of the machine.

' During this cycle, the form 210 is moved up into the upper, stretching the same against the pull of the grippers ano. thereby duplicating the pulling over and ,side lasting stresses and causing the upper, lining and counter to be shaped about the heel end of the form and be bonded together under conditions which are similar to those t9 clockwise movement of the lever 286.

' move it rearwardly, as viewed in Fig; 18, thereby which they will be subjected in the subsequent lasting operation. As the form moves into the upper, the margin of the heel seat face contacts the lining at a point between the top edge of the counter and the counter flange, and wipes the lining downwardly as it moves toward the flange. As/the heel seat face of the form approaches the counter flange., the bottom portion of the lining which overlies the counter flange is stretched inwardly beneath the bottom of the form by the bar 366 and the levers l368, 310 so that theA downwardly moving heel portion of the form will lay the lining smoothly against the counter flange. The flnal straightening of the toggle 286, 292 presses the heel end of the form against the support 58 with considerable force, thereby pressing down the gathers which formed about the head of the clamping nger 90.

As the form movesinto the upper, the clamping finger is moved out of engagement with the counter and'a short distance to the left, as viewed in Fig. 16, where it is locatedwithin an opening 21| formed in the heel portion of the form 210. The clamping finger is held in this position until an appropriate time during the next counter transfer operation by the latch 364. The form 210 is allowed to remain in the position shownin Fig. 16 a short interval while the quick-setting cement forms an initialbond between the shaped lining, counter and upper, after which the continued operation of the machine causes thevform to move from that position downwardly to the position shown in Fig. 18. As the form is moved out of the4 upper, the trip 408 releases the back seam grippers, and the trip 4|4 releases the treadles which are raised by the springs 43|, 432, thereby releasing the shank and tip line grippers, the toe gripper meanwhile being released by the Thev assembled upper can now be taken from the machine and a new series of operations started. If-

desired, a second counter may be dipped inthe cement and 'allowed to drain while the second cycle of machine operations is taking place and the molded upper removed from the machine.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. That method of making shoes which com'- prises immersing a counter in fluid cement, lifting the counter into 'a predetermined draining position, transferring the counter from the draining position to an assembling position,

' positioning a lined upper relatively to the supported counter, holding the rear part of the upper by its top margin, and while the upper is so held, wiping the rear part of the lining toward the counter flange.

2. That method of making shoes which comprises immersing ra counter in fluid cement, lifting the counter into a predetermined draining position, transferringv the counter from lthe draining position to an assembling position, positioning an upper in predetermined relation to the counter,l gripping the opposite ends of the back seam of the upper, and forcing a form into the upper to shape the upper while it is so held.'

3. That method of assembling and shaping uppers which comprises asembling an upper and a counter, stretching the assembled upper in a lengthwise direction and, while the upper is under lengthwise tension, exerting pulls on the lasting margin at selected side portions to cause the heel portion of the assembled upper-.to set with the upper under lengthwise and heightwise stresses similar to those to which it will be subjected during the subsequent lasting operation. 4. That4 method of assembling and shaping uppers which comprises assembling an upper and a counter, supporting the upper at the heel end, holding the lasting margin of the upper in opposite shank portions, in the opposite tip line portions and at the toe end, stretching the upper in a lengthwise direction and concomitantly stretching the upper in a heightwise direction to cause the heel portion of the assembled up- 'per to set with the upper under lengthwise and `heightwise stresses similar to those to which it will be subjected during the subsequent lasting operation. i

5. That method of assembling and shaping uppers which comprises assembling an upper and a counter, supporting the upper at the heel end, holding the lasting margin yof the upper in opposite shank portions, opposite tip line portions and at the toe end, stretching the upper in a lengthwise direction, inserting a form into the upper, and imparting relative heightwise movement to the form and the upper to cause the heel portion of the upper to set with the upper under lengthwise and heightwise tension similar to that to which it will be subjected during the subsequent lasting operation. 6. That method of assembling and shaping uppers and hanged counters ofi the last which A comprises assembling an upper and a counter, supporting the .rear portion of the assembled upper, stretching the upper in a lengthwise direction, inserting a form into the upper with a combined heightwise and heelward movement, stretching the marginal portion of the lining adjacent the counter flange inwardly beneath the heel portion of the form, andurging the forepart of the form upwardly from the lasting margin and the heel portion of the form rearwardly and downwardly to lay the lining smoothly over the counter flange and to shape the heel end of the upper- 7. That method of assembling an upper and a molded counter which comprises mechanically lasting operation, and pressing the upper, counter, and lining together while subjected to these stresses to cause the heel portion of the counter to set under lasting conditions.

8. That method of assembling and shaping shoe uppers which comprises supporting the heel end of an assembled upper, gripping the upper in the opposite shank portions, inserting a form in the upper and imparting relative heightwise up in the upper .stresses similar to side lasting stresses and at the same time moving the form rearwardly to shape the heel portion of the upper? v y while it is subjected to the side lasting stresses.

10. That method of assembling and shaping shoe uppers which comprises supporting the heel end of an assembled upper, holding the lasting margin of the upper adjacent the opposite ends of the tip line andat the toe end, inserting a `shoe uppers which comprises supporting the heel end of an assembled upper, holding the lasting margin of the upper adjacent the opposite ends of the tip line and at the toe end, imparting relative movement to the grippers and the heel end support to stretch the upper in a lengthwise direction, inserting a form into the upper yand urging theV toe end of the form upwardly to set up in the upper stresses similar to pulling over stresses, andmoving the heel end of the form rearwardly and downwardly to wipe the upper and shape its heel end while subjected to the stresses.

l2. That method of assembling and shaping shoe uppers which comprises supporting a cement-treated counter by its sole attaching flange, positioning a linedy upper in determinate relation to the counter heightwise thereof and supporting theyupper in that position, smoothing the lining against the inner surface of the counter, stretching the marginal portion of the Alining adjacent `to the sole attaching counter movement to the form and the gripped portion l of the upper to setfup in the upper stresses similar to side lasting stresses, and concomiv tantly imparting relative/lengthwise' movement to the form and the upper to shape 'the heel portion of the upper about the heel end of the 'form while the upper is subjected to the stresses. 9. That method ofv assembling and shaping shoe uppers which comprises supporting the heel end of an assembled upper, holding the upper,v

in opposite shank portions, inserting a form in the upper and urging the form upwardly to set flange-inwardly above the flange, and moving a `forrn downwardly against the stretched lining to lay it smoothly over the iiange.

13. That method of assembling and shaping shoe uppers which comprises supporting a cement-treated counter by its sole attaching flange, positioning a lined upper in. determinate relation to the counter heightwise thereof and. supporting the upper in that position, smoothing the lining against the inner surface vof the counter, collecting the excess material in the marginal portion of the' lining in gathers over the heel end of the counter ange, and moving a form into the heel portion of the upper to press the gathers against Athe counter. iiange.

14. That method of assembling and shaping shoe uppers which comprises supporting a cement-treated counter by its sole attaching flange, positioning a lined upper indeterminate relation to the counter heightwise thereof and supporting the upper in that position, smoothing the lining against the inner surface of the counter, collecting the excess material in the marginal portion of the lining in gathers over the heel end of the counter flange, stretching the marginal portion of the lining adjacent tothe counter flange inwardly above the counter flange, and moving a form rearwardly and downwardly into the heel end` of the upper to wipe the lining heightwise of the upper and to press the marginal portion of the lining against the counter flange.

15. A machine for shaping the heel end of an assembled upper oi the last comprising means for supporting an assembled upper, an upper shaping form, and means for moving the shaping form into and out of the supported upper.
